Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corridor indicator lamps face visibility issues in curved corridors, areas with exposed brickworks, or near wall projections, leading to potential oversight due to obstruction.
Innovation Solution
A corridor indicator lamp design featuring a base assembly with compartments and an extension unit that can be mounted to increase visibility, including a set with adjustable height covers and a retrofit kit to enhance visibility in challenging environments, utilizing extension walls and pockets for light distribution and shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the corridor indicator lamp is mounted on a standard base assembly, then the device complexity is low and manufacturing is easy, but the visibility is insufficient in curved corridors or areas with wall projections
Solution Approach 1:
The indicator lamp is divided into a base assembly and a separate extension unit. The extension unit can be attached to the base assembly when additional visibility is needed in curved corridors or areas with obstructions. This segmentation allows the system to maintain simplicity for standard installations while providing enhanced visibility options when required.
Solution Approach 2:
The system transitions from a static base assembly to a dynamic configuration by allowing the optional attachment of an extension unit. This enables the device to adapt its effective height and visibility characteristics based on the specific installation environment, whether straight corridors or curved areas with projections.
2Adaptability or versatility
If the corridor indicator lamp uses a fixed height design, then the manufacturing precision and ease of manufacture are high, but the adaptability to different mounting locations is limited
Solution Approach 1:
The indicator lamp system is segmented into a standard base assembly and an optional extension unit. This allows manufacturers to produce a simple, standardized base assembly that is easy to manufacture, while providing the flexibility to add height adaptation through the separate extension unit when specific mounting locations require it.
Solution Approach 2:
The base assembly is designed as a universal platform that can function both as a standalone unit for standard installations and as a base for the extended configuration when additional height is needed. This multi-functionality allows a single base design to serve multiple mounting scenarios.
3Length of moving object
If the corridor indicator lamp is positioned close to the wall, then the device complexity is low, but the visibility distance is insufficient in obstructed areas
Solution Approach 1:
Instead of increasing the lateral projection of the indicator lamp, the solution extends the visible information vertically away from the wall surface. The extension unit creates an elevated display position that projects information into the corridor space, allowing visibility over obstructions without increasing the device's footprint on the wall.

AI summary
The invention relates to a corridor indicator lamp (1). The corridor indicator lamp (1) comprises a base assembly (12) which includes a plurality of compartments (4) and a plurality of separator walls (46). The compartments (4) are open towards a front side (14) of the corridor indicator lamp (1), the separator walls (46) separate at least some of the plurality of compartments (4). In order to improve visibility of the indicator lamp (1) when it is mounted at locations where it may be partly obscured from view, an extension unit (54) is provided according to the invention. The extension unit is configured to be mounted to the base assembly (12) and has a plurality of extension walls (58). When the extension unit (54) is mounted to the base assembly (12), at least some of the plurality of compartments (4) are extended in a direction pointing away from the base assembly (12), thus increasing the height (22) of the corridor indicator lamp (1). An at least partly transparent cover (16) may be further provided, which is adapted to receive the extension unit (54) and may be configured to be attached to the base assembly (12) as a replacement to a flatter cover (16).
